신성웅,김봉수,성덕규,정영,유희정,조수철 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

학습장애를 가진 86명의 초등학교 남학생과 52명의 정상적인 초등학교 남학생의 자아상과 우울,그리고 상태-특성 불안에 관하여 피어스-해리스 자아상 척도, 소아우울척도(이하 CDI), 상태-특성불안 척도(이하 STAI)를 이용하여 조사하였다. 피어스-해리스 자아상 척도의 총점에서는 두 군 사이에 차이가 발견되지 않았으나, 지적 및 학업 상태 항목과 신체적 외모, 행복과 만족 소척도에서는 두 군 사이에 의미 있는 차이가 관찰되었다. 소아우울척토의 총점과 그 소척도 중 부적합함, 무쾌감증, 부정적인 자기 존중 항목에서 학습장애 아동이 정상 아동보다 더 높은 점수를 나타내었다. 상태불안은 정상 아동보다 학습장애 아동에서 높게 보고되었으나 특성 불안에 대해서는 차이를 보이지 않았다. 정상 아동에서는 나이에 따른 자아상과 우울척도, 불안척도의 의리 있는 변화가 관찰되지 않았으나, 학습장애 아동에서는 피어스-해리스 자아상 척도와 그 소척도의 대부분이 통계적으로 의미 있게 감소하였고, 소아우울척도의 부정적 감정과 무쾌감증, 부정적 자기 평가, 상태 불안, 특성 불안 등은 연령과 의미 있는 양의 상관관계를 나타내어서 학년이 올라갈수록 자아상은 저하되고 우울과 불만은 느끼는 강도와 범위가 증가하는 양상을 보였다. 두 군 모두에서 소아우울척도는 피어스-해리스 자아상 척도의 총점과 그 소척도들과 의미 있는 역의 상관관계를 나타내었고, 상태불안과 특성불안과는 정의 상관관계를 나타내었다. 조사 결과 학업과 관련된 자아상의 문제와 자신이 남들과 당당히 맞설 수 있는 자신감의 문제가 학습장애에서 더 많이 나타났고, 나이가 들수록 자아상이 저하되며 불안과 우울은 증가하는 것으로 나타났다. 회귀분석 결과 학습장애 아동의 자아상을 설명하는 변수들로는 나이와 자아상 척도의 행동문제, 지적 및 학업상태, 불안, 인기도, 행동과 만족, 그리고 소아우울척도의 부적합함, 대인관계문제, 부정적 자기-존중 및 상태 불안인 것으로 드러나서 학습 장애 아동의 자아상은 학업 문제와 자신을 또래와 비교하여 겪는 스트레스로 인해 부정적인 영향을 받는다는 것이 확인되었다. 결론적으로 학습장애를 가진 초등학교 남학생은 정상 초등학교 남학생보다 자아상이 낮고 우울과 불안을 더 많이 느끼며, 이런 차이는 학년이 올라갈수록 커졌다. 학습장애에서 우울증과 불안 장애가 많이 동반되기 때문에 임상에서 학습장애 아동을 치료할 때 정서 장애의 동반 여부를 확인하고 이를 적극적으로 치료하는 것이 중요한 과제이다. 중심단어 : 학습장애 ㆍ 자아상 ㆍ 상태-특성 불안 ㆍ우울증. We investigated the self-concept, subjective depression, and state-trait anxiety of the school boys with learning disabilities (abbr. LD, n=86) and compared them with normal boys (n=52) using Piers-Harris Self-Concept Inventory, Child Depression Inventory (abbr. CDI), and State-Trait Anxiety In-ventory (abbr. STAI). With regard to Piers-Harris Self-Concept Inventory total scores, there was no significant difference between two groups, but normal boys showed higher scores in intellectual and school status, physical appearance, and happiness-satisfaction subscales than patients with LD. The male patients with LD showed significantly higher ratings in CDI total scores, and CDI subscales - ineffectiveness, anhedonia, negative self-esteem than normal children. The patients with LD reported significantly higher state anxiety, but not trait anxiety. Correlation analyses revealed that self-concept decreased over time, and depression-anxiety increased across grades in the patients with LD, but not in normal children. Especially, negative mood, anhedonia, negative self-esteem subscales of CDI, and state-trait anxiety showed significant positive correlation with grades. In both groups, CDI scores were inversely correlated with Piers-Harris Self-Concept and positively with State-Trait anxiety. In conclusion, self-concept problems which were related with school achi-evement and self-esteem were more abundant in the patients with LD than normal children, self-image problem, depression and anxiety increased across grades. According to regression analysis, age, behavior subscale, intellectual - school status, anxiety, popularity, happiness- satisfaction, CDI-ineffectiveness, interpersonal problem, negative self-esteem, and state anxiety could explain the self-concept in the patients with LD, not in normal children. So, the self-concept of the patients with LD were found to be related to the school achievement and stress when comparing with peers. In conclusion, elementary school boys with LD showed lower self-concept, higher depression and anxiety, and these differences increased across grades. Since the patients with LD have concomitant depression and anxiety disorders, it is important that comorbidity with emotional problems should be explored and managed properly. KEY WORDS : Learning disability ㆍ Self-concept State ㆍ trait anxiety ㆍ Depression.

신홍규,김남수,김웅겸,홍남표,김병희,김헌영 江原大學校 産業技術硏究所 2004 産業技術硏究 Vol.24 No.A

In the study, we have developed a straightening system for the SUS 304 micro wires that are normally used in the medical and semi-conductor fields. To apply heat to the micro wires, we introduced the direct wire heating method which generates the thermal energy by the electrical resistance of the wire itself. To avoid the deterioration of the wire surface by the environment, such as the oxidation or the hydration, the N_(2) gas was filled in the glass pipe in which the straightening process was being performed. A precision tension meter was also attached to control the tension of the wire during the heating and straightening process. In order to control the straightening process, several experimental investigations with varying the tension, the feeding velocity and the temperature (current) was carried out. As a result of experiments, we obtained the optimal processing conditions satisfying the straightness requirement of the micro wires.

신희웅,이현 대전대학교 한방병원 2001 惠和醫學 Vol.10 No.1

About the acupuncture & moxibusrion therapy of Chest pain(胸痛), the results are obtained as follows: 1. Ever since 'cold' is refered to the cause of a disease in 《Nae-Kyung》, until Ming-Qing period, yin-noxious vapor(cold, wind-cool) internal depression which occurs because of the chest yang deficiency was seen as a chief cause and mechanism. However, recently, cold noxious vapor internal invasion, emotional imbalance, irregularity of diet, old age debility was referred and it's said that because of debility of the five visera and yinyang-vital energy and blood, functional disorder, cold condensation, energy stagnation, blood stasis, moisture appear therfore the chest pain exalts. 2. The most frequently used channel in the acupuncture & moxibustion therapy for chest pain(胸痛) were Pericardium meridian(心包經) and Conception Vessel Meridian(任經). Also, the most commonly used channels in order are Bladder meridian(膀胱經). Kidney meridian(腎經). Spleen meridian(脾經), Liver meridian(肝經), Lung meridian(肺經), Stomach meridian(胃經). 3. When we do a acupuncture & moxibustion therapy for the chest pain(胸痛), Naegwan(內關), Chok-Samni(足三里) were the most useful ones. In addition, the most commonly used points in order are Yoˇn-gok(然谷), Shinmun(神門), Kansa(間使), T'aech'ung(太衝), Chung-wan(中脘), Sang-wan(上脘), Chigu(支溝) ), T'ae-gye(太谿), Taejong(大陸), Haenggan(行間), Oˇje(魚際), T'aeyoˇn(太淵), Koˇgwol(巨闕), T'aeback(太白 ). 4. Angina Pectoris which is a subtitute of the chest pain in a narrow sense was known as 'in conclusion death and unable treatment', and in chest pain of a wide sense, variety of the acupoint based on the theory of visera-stae doctrine and meridianology was used. Among those acupoints, Naegwan(內關) and Chok-Samni(足三里) were used much. 5. The acupoints which is used when disease which occurs with the chest pain appears, was based on the theory of viscera-state doctrine and meridianology. Also it was used in many acupoints. 6. When the chest pain which occurs because of external damage appaears, acupunctured on Chigu(支溝), Kansa(間使), in the chest pain which occurs because of internal damage, acupunctured on Chu'ng-wan(中脘), Chok-Samni(足三里), Choˇnjung(中脘), in cold noxious vapor condensation, acupunctured on Naegwan(內關), Kwanwon(關元), in energy stagnation and blood stasis, acupunctured on Choˇnjung(단中), Koˇgwol(巨闕), in stagnation of phlegm, acupunctured on Chung-wan(中脘), P'ungnyung(豊闕), in heart spleen yang deficiency, acupunctured on Shimsu(心兪), Pisu(脾兪) and in impairment of liver and kidney, acupunctured on Shinsu(腎兪), Kansu(肝兪).

푸리에 변환과 웨이브렛 분석을 통한 주의력결핍ㆍ과잉운동장애아동과 정상아동의 사건관련전위 비교 연구

신성웅,박진형,김희찬,조수철 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

주의력결핍 ㆍ 과잉운동장애 아동과 정상 아동의 청각적 집중 과정의 차이를 비교하기 위해 13명의 남자 환자와 8명의 정상 남자아이에게 청각적 주의집중 과제를 제시하고 사건관련전위를 푸리에 변환과 웨이브렛 분석법으로 비교 조사하였다. 각 군 아동의 표준자극과 표적자극에 대한 사건관련전위 파형을 푸리에 변환을 통해 주파수 차원에서 서로 비교하였고, 각 군 안에서 표적자극과 표준자극을 주었을 때의 진폭을 비교하였다. 표준자극에 대해서는 거의 대부분의 주파수와 좌측 위치에서 주의력결핍 ㆍ 과잉운동장애 아동이 정상아동보다 의미 있게 높은 전압을 나타내었다. 반면 표적자극에 대해서는 주의력결핍 ㆍ 과잉운동장애 아동이 정상 아동보다 더 높은 전압은 보이는 경우가 의미 있게 감소하였고 정상 아동이 주의력결핍 ㆍ 과잉운동장애 아동보다 큰 진폭을 나타내는 경우는 의미 있게 증가하였나. 이런 결과는 주의집중을 반영하는 Nd파형의 푸리에 변환 결과에서도 나타났다. 즉 주의력결핍 ㆍ 과잉운동장애 아동은 무시해야 하는 자극에 대해서는 정상 아동보다 지나치게 강한 반응을 보이지만 정작 과제를 수행해야 하는 자극에 대해서는 정상 아동보다 더 약한반응을 보이는 경향을 보였다. 주의력결핍ㆍ 과잉운동장애 아동은 정상 아동 보다 표적자극에 의한 진폭 증가를 보인 전극과 주파수 영역이 적었을 뿐 아니라 일부 파형은 표준자극을 주었을 때보다 표적자극을 주었을때 오히려 진폭이 의리 있게 감소하여서 이들이 표적 자극에 대해 활성이 억제됨을 알 수 있었다. 정상 아동들은 표준자극보다 표적자극에 대해서 거의 모든 전극 위치와 주파수 대역에서 의미 있는 진폭의 증가를 보였으나 전전두엽과 전두엽의 전극에서는 주의력결핍 ㆍ 과잉운동장애 아동이 더 큰 진폭을 보이는 경우가 관찰되었다. 웨이브렛 분석 결과 표준자극에 대해서는 주의력곁핍 ㆍ 과잉운동장애 아동이 정상 아동보다 자극이 제시된 후 0∼300msec 사이에 일어나는 전위가 통계적으로 의미 있게 컸다. 이런 차이는 주로 전전두엽과 전두엽 앞쪽, 그리고 측두엽 일부와 후두엽에서 두드러졌다. 그러나 두정엽과 중앙 영역의 전극들은 특히 300∼370msec 이내에 일어나는 전위에서 정상 아동이 더 활발한 전기 활동을 나타내었다. 표적 자극에 대해서는 두 군 모두 표준자극보다 전기 활성이 더 증가한 양상이었다. 표적자극에 대해서 주의력결핍 ㆍ 과잉운동장애아동은 전전두엽과 전두엽 영역에서는 여전히 정상 아동보다 더 활발한 전기 활성을 보였으나 두정엽과 측두엽에서는 정상 아동이 더 큰 진폭을 나타내었다. 이로써 주의력결핍 ㆍ 과잉운동장애 아동은 무시해야 하는 자극에 대해서는 지나친 반응을 보이며 주의집중을 필요로 하는 자극에 대해서는 정상 아동보다 저하된 반응을 보이는 것이 확인되었다. 이와 함께 푸리에 변환 등 주파수 차원 분석법과 웨이브렛 분석 방법의 유용성을 알아보았다. 중심 단어 : 주의력결핍 ㆍ 과잉운동장애 ㆍ사건관련전위 ㆍ푸리에 변환 ㆍ 웨이브렛 분석. Using Fourier transformation and wavelet analysis, we compared the auditory event-related poten-tials of the patients with attention deficit-hyperactivity disorders (abbr. ADHD, 13 boys) and normal control children (8 boys) Amplitudes of the event-related potentials which were calculated via Fourier transformation were compared between the groups and between conditions (non-target versus target) in each group. To the non-target stimuli, the patients with ADHD showed significantly greater amplitudes across almost all of the electrode sites and frequencies. To the target stimuli, the incidents which ADHD patients showed much higher amplitudes than normal controls significantly decreased, while those of the reverse results increased significantly. These results were consistent with the comparison results about negative difference wave (abbr. Nd wave) using Fourier transformation. In summary, it was proved that non-target stimulus which should be ignored elicited more robust electrical response from the patients with ADHD than normal children, but the target stimulus which required active processing did much less electrical activity in the patients. For the patients, they showed much inhibited electrical response to the target stimuli in some electrodes and frequency ranges. Normal children were more strongly stimulated by the target stimuli in almost all electrodes and frequency ranges than the patients, but less in prefrontal leads and frontal leads. Wavelet analysis results proved that early responses (0-300msec) to the nontarget stimuli of the patients were significantly greater than the normal controls in prefrontal, anterior frontal, some parts of temporal, and occipital lobes and that late response (300-370msec) were significantly lesser than normal children in parietal and central electrodes. Target stimuli elicited significantly higher electrical activity in both group than non-target stimuli did. Prefrontal and frontal lobes showed stronger responses in the patients than normal children irrespective of stimulus condition, but parietal and temporal lobes did higher activities in normal children than the patients only to the target stimuli. In conclusion, the patients wish ADHD showed much greater responses to the stimuli which should be ignored, but failed to activated the necessary processes to the target stimuli. Also, we found that the frequency-dimension analysis and wavelet analysis were useful for the signal processing such as event-related potentials. KEY WORDS : Attention deficit hyperactivity disorder ㆍ Event related potentials ㆍ Fourier transformation ㆍ Wavelet analysis.

電力系統 解析에 相座標系의 適用에 관한 硏究

金武雄,서희석,申明澈 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.1

In resent times, the analysis of power system by the method of phase coordinates which uses the phase quantites directly has been studied extensively instead of the method of symmetrical components. In this paper, the power system components are modelled in terms of the phase coordinates representation, and some results are obtained from the sample power systems based on this model. In addition, in order to demonstrate further effectiveness and reliablity of phase coordinate method, its results are compared with those from the method of symmetrical components. In simulation, simple models are used for the analysis of power system, but this method can be extended to any number of systems.

Prediction of Protein Structure and Interaction by GALAXY Protein Modeling Programs

Woong-Hee Shin,Gyu Rie Lee,Lim Heo,Hasup Lee,Chaok Seok 한국구조생물학회 2014 Biodesign Vol.2 No.1

In this review, recently developed GALAXY protein modeling programs are introduced and advantages and disadvantages of these programs for both program users and method developers are discussed. The GALAXY package consists of the template-based modeling program GalaxyTBM, the loop/terminus modeling program GalaxyLoop, the model refinement program GalaxyRefine, the homo-oligomer prediction program GalaxyGemini, and the protein-ligand docking program GalaxyDock. These programs have been tested with some success in community-wide competition Critical Assessment of Techniques for Protein Structure Prediction (CASP) experiments. For the development of these programs, modeling problems have been posed as global optimization problems of designed energy functions. The free energy functions of GALAXY have been carefully designed by combining physical chemistry principles and structure and sequence information. Efficient conformational search methods such as conformational space annealing and triaxial loop closure have been employed. Freely accessible web servers of the modeling programs are available at http://galaxy.seoklab.org, and some programs can be downloaded from http://galaxy.seoklab.org/softwares.

Localized surface plasmon-enhanced light emission using platinum nanorings in deep ultraviolet-emitting AlGaN quantum wells

Shin, Hee Woong,Son, Kyung Rock,Kim, Tae Geun OPTICAL SOCIETY OF AMERICA 2016 Optics letters Vol.41 No.1

<P>We report the enhancement of deep ultraviolet emissions from AlGaN-based quantum wells (QWs) using energy-matched localized surface plasmons (LSPs) in platinum (Pt) nanoring arrays. The peak resonances of the extinction spectra were shifted to the red spectral region as the nanoring diameters increased, and the Pt nanorings with a diameter of 325 nm exhibited strong photoluminescence (PL) resonance at 279 nm. The emission enhancement ratio was calculated to be 304% in peak PL intensity when compared to that of the bare AlGaN QWs; this is attributed to the strong coupling of QWs with LSPs from the Pt nanorings.
